      • createSslHandler

        public static io.netty.handler.ssl.SslHandler createSslHandler​(io.netty.buffer.ByteBufAllocator allocator,
                                                                       String host,

                                                                throws Exception
        Creates a Netty SslHandler instance for use in Transports that require an SSL encoder / decoder. If the given options contain an SSLContext override, this will be used directly when creating the handler. If they do not, an SSLContext will first be created using the other option values.
        Parameters:
        allocator - The Netty Buffer Allocator to use when Netty resources need to be created.
        host - the host name or IP address that this transport connects to.
        port - the port on the given host that this transport connects to.
        options - The SSL options object to build the SslHandler instance from.
        Returns:
        a new SslHandler that is configured from the given options.
        Throws:
        Exception - if an error occurs while creating the SslHandler instance.
      • createJdkSslContext

        public static SSLContext createJdkSslContext​(SslOptions options)
                                              throws Exception
        Create a new SSLContext using the options specific in the given TransportOptions instance.
        Parameters:
        options - the configured options used to create the SSLContext.
        Returns:
        a new SSLContext instance.
        Throws:
        Exception - if an error occurs while creating the context.
      • createJdkSslEngine

        public static SSLEngine createJdkSslEngine​(String host,
                                                   int port,
                                                   SSLContext context,
                                                   SslOptions options)
                                            throws Exception
        Create a new JDK SSLEngine instance in client mode from the given SSLContext and TransportOptions instances.
        Parameters:
        host - the host name or IP address that this transport connects to.
        port - the port on the given host that this transport connects to.
        context - the SSLContext to use when creating the engine.
        options - the TransportOptions to use to configure the new SSLEngine.
        Returns:
        a new SSLEngine instance in client mode.
        Throws:
        Exception - if an error occurs while creating the new SSLEngine.
      • createOpenSslContext

        public static io.netty.handler.ssl.SslContext createOpenSslContext​(SslOptions options)
                                                                    throws Exception
        Create a new Netty SslContext using the options specific in the given TransportOptions instance.
        Parameters:
        options - the configured options used to create the SslContext.
        Returns:
        a new SslContext instance.
        Throws:
        Exception - if an error occurs while creating the context.
